星形母细胞瘤是恶性程度最高的星形细胞肿瘤,由分化差的肿瘤性星形细胞构成。组织学特点包括细胞多形性、核不典型、高分裂活性、血管血栓形成、微血管增生和坏死。胶质母细胞瘤主要累及成人,好发于大脑半球。胶质母细胞瘤可从弥漫型星形细胞瘤WHOⅡ级发展而来(继发性胶质母细胞瘤),但更常见的是临床病史短,没有低恶性前期病变的原发性胶质母细胞瘤。

结果四脑室肿瘤以髓母细胞瘤、室管膜瘤和星形胶质瘤多见,肿瘤与发病年龄关系密切。
Results the most common neoplasms were medulloblastoma and ependymoma and astrocytoma in the fourth ventricular. Some tumors had specific patients age.
结论R CAS1是人脑星形细胞瘤的新的肿瘤相关抗原,其表达与胶质母细胞瘤的形成相关。
Conclusion RCAS1 is a new tumor-associated antigen of human astrocyte tumors, whose expression correlated to the malignant transformation of glioblastoma.
多形性胶质母细胞瘤起源于星形胶质细胞,这是胶质细胞的一种。促使正常工作的星形胶质细胞转变为肿瘤细胞的原因尚不得而知。 。
GBM M originates from astrocytes, which are a type of glial cell. The factors that cause normal-functioning astrocytes to become cancerous is not well understood.
